l fixed to a pivoted member and lcooperates with a pair of laterally adjustable arms to hold an Object in osition upon the laterally adjustable arms w ich are adapted to engage the periphery ofthe object and which are also fixed to the pivoted member. A rack driven by a motor mounted on a pair of resiliently supported inclined members, may be actuated to tilt the pivoted member about its pivot to move an object to be transported into conveying position. Upon actuation of the rack, floor rests" formed on the inclined members engage the floor andremain in engagement therewith until the object being tilted into conveying position has been moved to a point where its weight will not tip the truck.

Other features and advantages of the in-l vention will become apparent from the following detailed description thereof, taken in conjunction with the accompanying drawings wherein, ,j

Fig. 1 is a side elevational view of an electrical truck embodying the features of this invention, showing"` a cable reel in place on the truck and the Hoor restsengaging the Hoor, and A f 'g'. 2' is an end elevational viewfof the apparatus shown inFig. 1. Y Referring now to the drawingswherein like reference characters designate the same parts throughout the severalv views, the'numeral 3 designates generally an electricalindustrial truck having the usual steering lever '4, a drive control lever 5, a brake controlling treadle 6 and ay housing-7 under which is mounted an electrical driving motor 8 of any usual electrical storage atteries for su ply- Ing energy to the' motor. For the sa e of clearness and since they do not form a part of the present invention the details of the aforesuitable type and cooperating gearing and l 'mentioned parts have not been shown.

The batteries and motor with its cooperating parts mounted in the housing 7 furnish power to drive wheels 12 and may be controlled through the lever 5 by an o erator 60 standing upon a circuit making tread e v13 of the usual type pivotally mounted on a transversely extending'member 14 to which longitudmally lextending supports 15 are secured.

Thedriving wheels 12 are mounted in any 65 well known manner and actuated by the motor 8 through suitable gearing notshown, and

a pair of trailer wheels 16y are mounted at the forward end of the truck. The supports 15 extend beyond the trailer wheels 16 and -70 are connected by a transversely extending member 17 to which are pivoted a pair of inclined members 18 which are supported at their upper ends by a member 19 which ex tends from one side'of the housing 7 to the 75 other side thereof transversely of the truck, and which is secured to the sides of the housing 7. A compression spring 20 is interposed between a portion 21 of the housing 7 and the mchned members 18 to normally urge the 80 members 18 into engagement with the member 19. Y l

A pair of L-shaped arms 24 are also pivoted to the member 17, their upper ends being provided with apertures 25 threaded in opposite B5 directions. A rod 26 is oppositely threaded to engage-the apertures 25 in the arms 24 and is rotatably j ournalled in apertures 27 formed in normally vertically extending members 28.

The outer ends ofthe rod 26 are provided 90 with hexagonal heads 29 adapted to be engaged by a wrench or like tool for rotating the rod to move simultaneously the arms 24 toward or away from the longitudinal center of the truck-along the threaded rod 26 and 95 the member 17 l j v A pair of racks 30 are pivotally attached to a bar 3 1 which 4extendsbetween the members 28. Motion may be imparted to the racks 30,

to cause the members 28 to pivot about the 100 member 17, by mea-ns of gears 32 mounted on a shaft 37 driven through suitable lreduction gearing designated generally by the numeral 33 driven by an electrical motor 34., A cross piece 35 secured at its ends to the members 18 supports the motor 34 which may be controlled by a control lever 36 mounted on the body of the truck in a convenient position for '1'0 operation by an operator standing on the treadle 13. The motor 34 is connected to the l "control lever 36 by conductors not shown.

' faces of the members 28. Fixed to the rod4l at a point intermediate itsends is an arm 43 having a hook 44 formed on the end. thereof for insertion in an aperture 45 of a cable reel v 46 of anv suitable and ordinary type.

' upon the ioor,

'It is believed that a clear understanding of the above described apparatus may` be had by reference to the following description of the operation thereof; Assuming'that itis desired to transport the cable reel- 46 from one place to another, an operator standing upon the treadle 13 a'nd controlling the truck bv means of the levers 4 and 5 and the treadle 6 may direct the truck to" a point directlv opposite the center of theflat side of the cable reelv 46. 1f the arms 24-have been ad'iusted transverselv of the truck to a position means of the heads Q9 formed on the threaded rod 26 and further assuming that the arm 43 has been adjusted vertically to the desired position, the truck may be driventoward the cable reelso that the arm 43 will enter the aperture 45 in the reel 1) of the arm 43 engages away from the truck. been driven to this s tart the motor 34 by means of the lever 36 thereby causing the rac right (Fig. 1). whereupon the arms 24 will engage the periphery ofthe reel 46. The relativemovement between the members-18 and the members 28 will, due to the weight ofthe reel, cause the springQO to be compressed. whereupon the left end of the member 18v will be moved downwardly into engagement .with the Hoor, and further movement of themember 18 being impossible the reely will be tilted tothe position shownin dotted lines in Fig. 1 which is the conveying position -ofthe reel.

After the reel has been transported to the desired location, the operation of the motor 34 mayv be reversed and the reel deposited the side of the reel may be released andfthe'truck backed away from the'reel.

It is to be noted that the spring 20 will be l for properly` vengaging the periphery of the cable reel by I and pass therethrough until the hook 44 formedon the left end (Fig.

After the truck has position the operator may 30 to be drawn to the.

whereupon the hooked arm 43 compressed due to the relative movement between the member 28 and the member 18 toI cause the left end of the members 18 to engage the floor thus preventing the truck from tipping.
